Winter was cold and long, sunshine hours were less and gale days were more in economic belt on north slope of Tianshan Mountains(EBNSTM) in Xinjiang Uygur Autonomous Region, the climate conditions are unfavorable to facility agriculture. It has great significance, study on the impact of climate change on climate suitability of facility agriculture, to adapt to climate change, scientific arrangements layout and made development planning for facility agriculture in EBNSTM. In this article, using climatic data from 35 meteorological stations in EBNSTM during 1961-2014, the fundamental spatial-temporal change characteristic of negative accumulated temperature of ≤0℃, sunshine hours from Dec. to next Feb. and gale days from Oct. to next Apr. were analyzed by using the methods of linear regression, accumulative anomaly, T-test and mixed spatial interpolation technology based on ArcGIS. And the change of facility agriculture climatic suitability was studied by combining with the climate division indices obtained through the actual investigation. The main results were as the follows: climatic conditions was very obviously different in different regions of EBNSTM, generally, negative accumulated temperature of ≤0℃ were more in alpine zones, followed by plain area, mid-mountain and low mountain zones were less. Sunshine hours from Dec. to Feb were more in mid-mountain and low mountain zones, alpine zones and plain area were less. Gale days from Oct. to Apr. were more in mountain valley areas, were less in mountain and plain areas. In recent 54 years, the three indicators showed a decreasing trend at the rates of-50.67℃·d·10y~(-1),-20.52h·10y~(-1) and-1.31d·10y~(-1), and they had mutation in 1988, 1987 and 1987 respectively. Under the joint effects of the above-mentioned climate factors, the areas of suitable area and sub-suitable area expanded 14466.0km~2 and 4929.7km~2 respectively, but the areas of unsuitable area decreased by 19395.6km~2 after 1988 than before in EBNSTM of Xinjiang.
